On old wood ranch fence boards near the coast, in coastal scrub habitat.
Thallus a thick rimose sorediate crust, the soredia varying from dull yellow to blue, C+O, K+Yish. Soredia do not appear to originate from discrete soralia, and no capitate soralia were observed as in L. simeonensis. Apothecia occasional in groups, emerging through the soredia, mostly plane, with sorediate rims and peach disks which tend to darken. Epihymenium with small POL+ orange and yellow crystals that are soluble in K. Pycnidia common in areas, absent in others; black, punctiform. Conidia filiform, curved, hyaline, 9-14×1-1.5µm.
Spores simple, hyaline, ellipsoid. Average size 11.3×4.5 (n=4).
Compare with Lecanora expallens in observation 315355; these two samples were collected growing together. This sample was much thicker with larger soredia, and has pycnidia which are not described from expallens. The conidia are consistent with simeonensis, but the chemistry is not. Spores are too small for simeonenensis, but are consistent with expallens. The blue coloration is also consistent with expallens
